Radio frequency coaxial connectors are components installed in cables or instruments, which are used to electrically connect or separate transmission lines. It is a series of mechatronics. Variety, specifications, depending on the mechanical structure, so as to ensure electrical characteristics, and other low-frequency connectors are essentially different. Radio frequency coaxial connector parts are mostly machined by turning machine, while assembly is manual. Product updates are slow. As an important component of electrical connector, it has high technical requirements and is a labor-intensive product.
